Following publication of the original article [1], the author reported that in the article the title "trial" was incorrectly written as "trail". In addition, Dr. Xiangqing Xiong's affiliation is only “the First Affiliated Hospital of Wenzhou Medical University” and is presented correctly in this correction article.

The original article [1] has been corrected.
